Earth is under siege from the alien menace known only by the name Cybercon and its legion of android forces, the Vorak. The Global Security Council convenes to address this problem, and calls upon Dr. Thaddeus Keane for assistance. They remember the aid they had received from Keane's special force, the Eagle Riders, in years past. Keane assures them that the Eagle Riders are still together, still strong, and armed with brand new weapons.
Eagle Riders is an adaptation of the Japanese series "Gatchaman II" and "Gatchaman Fighter", and is a sequel to the American show, "Battle of the Planets".
